| Lettuce is a leafy vegetable most consumed in Brazil, and is considered the basis for salads and can be grown by hydroponics system. Hydroponics is a viable alternative to be implemented, with benefits for soil conservation and preservation of water sources. This work aimed to study the market of trailers snacks in Pelotas to analyze the economic feasibility of deploying an enterprise for the production of hydroponic lettuce, minimally processed, on a farm located in the city of Pelotas. The trailers were classified as small, medium and large, according to the consumption of lettuce. From market analysis, facilities and greenhouses for hydroponics area for processing of lettuce with flowchart of activities and mass balance were designed. The lettuce is... |

| The tobacco drying greenhouses, in general, are made without any coating that ensures thermal insulation and avoid heat losses, resulting in a large consumption of firewood during the drying of the tobacco. The study aims to develop an economically viable project to the producer, to avoid excessive heat loss through the walls and ceiling of a tobacco dryer, aimed at fuel economy, reduced drying time and reduces costs in process. For the current project, we considered changes of Brazilian theoretical mode, where we developed a thermal insulation system in a dryer, reaching satisfactory results, with a large reduction in energy losses and firewood consumption, resulting in a decrease in the costs of the proceedings in general. Thus, began for the development... |

| Drying tomatoes with high initial moisture content have advantages such as: maintenance of mineral constituents, inhibition of the action of microorganisms, reduction of the cost of transportation, handling, and storage and is an alternative to the problems of waste disposal and pollution. Moreover, dried products, besides the more economical and affordable package, is an option for light and quick meals. Small and low cost tray dryers are hard to find in the Brazilian market. Producing your own dehydrated food is a practice used in many countries for domestic consumption, as a gift, for small-scale enterprises, because some people appreciate handmade products that are related to a healthier product, without additives. The present study aimed to dry... |
